'Hello,

'I followed the "tutorial" / article poste on the msdn.microsoft.com
'site located at this link
'<url>http://msdn.microsoft.com/library/default.asp?url=/library/en-'us/dnofftalk/html/office03072002.asp</url>

'But it does not compile. It gives an error for the declaration of
'Imports PowerPoint.PpSlideLayout
'Dim objPresentation As PowerPoint.Presentation

'and it does not recognize ppLayoutBlank. Has anyone else followed
'through this article to test out the code? I am new to VB .NET and the
'development of Office Add-Ins. I've posted my code below.

' When run, the Add-in wizard prepared the registry for the Add-in.
' At a later time, if the Add-in becomes unavailable for reasons such
as:
'   1) You moved this project to a computer other than which is was
originally created on.
'   2) You chose 'Yes' when presented with a message asking if you wish
to remove the Add-in.
'   3) Registry corruption.
' you will need to re-register the Add-in by building the
PowerPointAddInSetup project
' by right clicking the project in the Solution Explorer, then choosing
install.
